Transformations，Inc.在马萨诸塞州的多个地点，无论是生产还是定制家居环境，都拥有丰富的高性能住房建设经验。他们的大部分建筑使用小型分体式热泵（MSHP）进行空间调节。这项研究涵盖了5A区MSHP的长期性能;这是对一组8栋房屋进行长达3年的监测的结果。本研究探讨了MSHP的电力使用，在高性能住宅中使用简化（两点）供暖系统时室内温度和湿度的分布，以及开门/关门状态对温度分布的影响。使用简化的空间空调分布（通过使用MSHP）提供了显著的第一成本节约，用于抵消建筑物外壳中增加的投资。
Transformations, Inc. has extensive experience building their high performance housing at a variety of Massachusetts locations, in both a production and custom home setting. The majority of their construction uses mini-split heat pumps (MSHPs) for space conditioning. This research covered the long-term performance of MSHPs in Zone 5A; it is the culmination of up to 3 years' worth of monitoring in a set of eight houses. This research examined electricity use of MSHPs, distributions of interior temperatures and humidity when using simplified (two-point) heating systems in high-performance housing, and the impact of open-door/closed-door status on temperature distributions. The use of simplified space conditioning distribution (through use of MSHPs) provides significant first cost savings, which are used to offset the increased investment in the building enclosure.
